Enhanced Gas Separation Performance for H < sub > 2 < /sub > Purification Using MIL-68(ln)-NH < sub > 2 < /sub > /PES Mixed-Matrix Membranes
This study explored the incorporation of 10 wt. % of MIL-68(ln)-NH2 into PES membranes using a phase-inversion approach to enhance gas permeability and selectivity. The morphological, structural, and thermal properties of the resulting MOF/PES membrane were characterized using SEM, AFM, BET, XRD, FTIR, and TGA-DTG. Gas permeation experiments were conducted using different gases (CO2, N2, CH4, and H2) under different heating conditions (20-60 °C) to evaluate the gas permeability and selectivity of the MOF/PES membrane. The results showed that the incorporation of MOF into the mixed matrix membrane (MMMs) led to a 9% increa...

The link between autophagy and psoriasis
Acta Histochem. 2024 Apr 29;126(4):152166. doi: 10.1016/j.acthis.2024.152166. Online ahead of print.ABSTRACTAutophagy is a lysosome-dependent, self-renewal mechanism that degrades and recycles cellular components in eukaryotic cells to maintain the homeostasis of the intracellular environment. Psoriasis is featured by increased inflammatory response, epidermal hyperproliferation and abnormal differentiation, infiltration of immune cells and increased expression levels of both endothelial adhesion molecules and angiogenic mediators. Evidence indicates that autophagy has important roles in many different types of cells, such...
